This invention relates to a light fixture or lighting device and while the invention is capable of various applications, it preferably is designed for use with a small decorative 'lighting device, such as a Christmas tree, lamp set, or lamp socket. As is well known, electric lamp sets for Christmas trees are now very extensively used. With these sets of theprior art small lamp sockets are used in which the two conductors extend through the end of the socket. With this arrangement, if thelamp socket depends from the conductors the axis of the socketis vertical, or the open end is directed downwardly. It is now a very common practice to use reflectors on the lamp sockets, which reflectors are disposed in a plane substantially at right angles to the axis of the socket. The sockets therefore have heretofore had to be wired or fastened in some manner so that the axes thereof would be horizontal if it was desired to have reflectors disposed vertical, which is particularly desirable. With the conductors coming-out of the rear end of the socket the same were very apt to be pulled loose when it was attempted to twist the conductors around a twig or on some fastening means to properly dispose the sockets. On account of the disposition of the sockets having the conductors projecting through the ends it has not been possible to have a lamp depending into an open space in the tree and still be .in proper position to support a reflector.

It is an object of this invention, therefore, to provide a lighting device comprising a lamp socket with the conductors so arranged. that when the socket is suspended by the conductors it will have its axis in a substantial horizontal line.

It is afurther object of the invention to provide a lighting device comprising a lamp socket having tip and shell co'nductors, one of which projects through the side of the socket or in a directiontransversely of the axis of the socket.

It is a further object of the inventionto provide a light fixture comprising a lamp socket having a shell therefor with a tip contact and connductors secured, respectively to said shell and tip contact which project through a casing of said socket in a direction transversely of the axis of said socket.

It is more specifically an-object of the invention to provide a lighting fixture com prising a lamp sockethav'i'ng a shell and a tip contact, together with. a casing. surrounding said shell with conductors secured to said tip and shell extending through said casing transversely of the axisot said shell and inclined slightly in a direction toward the open end-of said shell.

These and other objects and advantages of the invention will be fully set forth in the accompanying drawings in which like reference characters refer to the sameparts through the different views, and in which,

Fig. 1 is a view inside elevation of a limb, such as the limb of a Christmas tree; 7 Fig. 2 is a central longitudinal section through the lamp socket used; and g V Fig, 3 is a vertical section taken on the line 3-3 of Fig. 2, as indicated by the arrows. x I

Referring to thedrawings, a lightingfixture or device is shown comprising a tal'lio shell 4 having threads 4 formed therein: adapted to have air-electric lamp screwed thereinto. The open end of the shell is shown as having a flaring rim 4. The" rear of the' shell carries an insulating plate 5 in which is secured a metallic tip-contact 6 adapted to be engaged by the tip contact on the lamp. The shell 4, with theparts 5 and 6 carried thereby, is snugly fitted in a casing- 7.- Thiscasin-g may be of any suitable insulating naterial, such as hard rubher or some artificial resin or other suitable substance. While the casing 7 maybe of various forms, in the embodiment of the invention illustrated,- the same is shown as of frusto c'onical shape having a thickened head or rim 7 at its front endand a ridge or-th-ickened portion 7 at one side thereof. A conductor 8 comprising; a wire with an insulating coating thereon extends through an opening 7 in the casing 7 and portion 7, which opening is inclined slightly forward towardthe open end of the casing and said conductor is connected to th'e shell 4;, preferably in the rear. of the flaring flange 4*, as shown. Another conductor 9, also illustrated asian'insulatcd wire, extends through an opening 7 in casing 7 and portion 7*, which opening also extends in an inclined direction towardthe open end of the casing and is connected at its inner end to the tip contact,; 6. .In the embodiment of the" invention illustrated -considerable spaceis shown in casing 7 in the rear of shell 4 but it will be understood that this space may be varied, as desired. Means such as a small eyelet or collar 13 may be placed on the conductor 19 adjacent the point where it-is connected to the tip "contact 6 sothat when said conductor is pulled I through the opening 7 the member 13 will contact the inside of the socket and prevent tension being applied to the tip connection. Conductors 8 and 9 are connected to the conductors forming a cord 10 and there will, as usual, he a series of lamp sockets connected to this cord; a

In operation, the cord 10 having the con ductors 8 and 9 and the lamp sockets thereon will be disposed about the Christmas tree so as to extend to various parts thereof, it

' the same also will be disposed with their being understood that, as usual, the cord 10 will have a plug secured thereto adapted to be connected to a standard supplying current.i i

As shown in .Fig. 1, thecord 10 may be socket for .Wound about a'limb 11 in helical form, or

it may be connected to-said limb inany suitable manner. When the sockets epend from the cord 10, as shown at the left hand end of Fig. 1, it will be seen that the easing 7 and the sockets will be held with their axes in substantially horizontal position. When the lamp, shown in dotted lines as 12, is inserted in the socket and the reflector, shown in dottedlines as 13, is held in position on the socket the. reflector will-be in substantial vertical position so that the light from lamp 12 will be reflected forwardly. The sockets which are disposed at the edge of the tree or adjacent the ends of the limbs can readily be positioned by merely having the loop formed by cord 10 and the con .ductors 8 and 9extend over the end of the limb 11. This forms a very convenient means of attachment and it is unnecessary to use a wire or other fastener to hold the sockets. Vhen the sockets are so positioned,

axes in substantially horizontal :position. lVith the conductors 8 and 9 thus projecting from the side of the sockets transversely of the axis thereof, it is seen that the sockets naturally hang. in correct position and have their reflectors properly positioned thereon. It will also be noted that the'sockets can'be suspended from a limb so as to hang into an 0 on space on the tree so that a light can be isposed in said open space and the socket thereof will also have its axis in subparts without departin said casino stantially horizontal position without any extra fastening or holding means. WVith the sockets of the prior art, it was often at tempted to twist the conductors thereof about twigs. or to secure the same by pieces is avoided and yet the reflectors are disposed in the desired sition. By having the passages 7 and in casing 7 inclined, any pu l or strain occurring on conductors Sand 9 is taken up largelyv by the Walls of the little stress laced on the contacts or connections with t e tip and shell.

"From the above description it is seen that applicant has provided a very simple and casing 7 or said. passages so that thereis efficient lighting device and one WlllCh is a 1 greatimprovement upon those of the prior art and constitutes a great advance in the art. As above set forth, the device ossesses many advantages and has a high d2 ree of utility. The device has been amply emonstrated in actual practice and found to be very successful and efficient.

. It will, oficourse, be understood that various changes may be made in the form, de-

tails, arrangement and proportions of. the from the scope. of applicants invention, w ich, generally stated, consists in a device capable of carrying out the objects above set forth, in the novel parts and combinations of parts disclosed and defined in .the appendedclaims.
